Bacterial infections are increasingly difficult to treat with antibiotics due to antibiotic resistance. Knowledge on how of bacteria multiply needs to be profoundly expanded as a requirement for the development of new methods for the discovery of

In the present era, pollution of water, soil and air with heavy metals is increasing rapidly. Industrialization and technological advancement have caused serious damage to the ecosystem by releasing large quantities of heavy metals (i.e., cadmium, chromium,

The development of bacterial infections on and around biomedical materials, ranging from hip implants to wound dressings, is a large and growing problem. Biomaterial-associated infections are challenging to treat because bacteria tend to form colonies, called biofilms,

Bacteria, whether beneficial or harmful, must adapt to changes in their environment in order to survive. This is especially true for bacteria that reside within the human respiratory tract. The bacterium nontypeable Haemophilus influenzae, or NTHI, asymptomatically

The chloroplast, known to have originated around a billion years ago, is now one of the most recognizable characteristics of the plant cell. After the engulfment of the ancient cyanobacterium by the eukaryotic host cell, the former

Sponges are second dominant to corals in terms of biomass in many coral reef ecosystems. They play a significant role in maintaining the health of reef ecosystems through processing of waste generated in the system by continuous

Xanthomonas citri subsp. citri (X. citri) is a Gram-negative bacterium and the etiological agent of citrus canker, a severe disease that affects all the commercially important citrus varieties with worldwide distribution. The best method to control the

When in contact with a hot object, our immediate response is to withdraw our hand. This instinctive reaction is an example of how external environment shapes our actions. In a similar fashion, bacteria are constantly monitoring and

Failure to assemble a division septum occurs in Escherichia coli cells when their supply of FtsZ is blocked. FtsZ, ancestor of eukaryotic Tubulin, is the main component of the divisome, the molecular machinery that drives septation in

Bacteria are able to utilize various carbon sources, and change the intracellular metabolic fluxes depending on the availability. Whereas much effort has been taken to understand the underlying mechanisms, most parts of them are still elusive and

Public Health authorities sound the alarm over the increasing bacterial resistance to antibiotics and project a dark picture back to the pre-antibiotic era. One avenue of solutions proposed is to identify the spectrum of susceptibility to antibiotics

Humans have a symbiotic relationship with microbes that reside in and on our bodies. The human digestive tract contains as many as 1014 of bacterial cells, making it one of the densest and most diverse microbial communities

Bacteria are the smallest free-living (self-replicating) organisms. Most swim in aqueous media by rotating flagella, long thin filaments driven at their base by rotary motors. In most cases, the filaments are helical and extend out into the

Microorganism detection is an essential task for wide range areas of human activities driven by economic and healthcare factors. Total Viable Count (TVC) method is a benchmark in microbiology, which is based on visual observation of the

Since the first six decades of the twentieth century,the autonomous unicellular organisms, bacteria with unimaginable computational and evolutionary capabilities along with collective behavior has been running. Do not consider them to be small, simple and stupid because

In the event of bacterial infection, large numbers of neutrophils migrate from the blood to the infected site in order to destroy the invading microorganism and thus protect the host. The neutrophils removed from the peripheral blood

Chagas disease caused by the parasite Trypanosoma cruzi, is considered by the World Health Organization (WHO) one of the most neglected tropical diseases worldwide. Prevalent in developing countries, it has a major social and economic impact in

The rapid emergence of antibiotic resistance is a worldwide crisis, endangering the efficacy of antibiotic treatment. A recent article in Scientific America (December 16, 2014) highlights the importance of developing strategies for reducing antibiotic resistance and prolonging

Do you know that bacteria, microscopic organisms not visible by the human naked eye, can live in complex communities just like we humans do? They are perfectly able to stick together, grow and multiply in what is

Gene manipulation tools are routinely used to create genetically engineered bacteria to understand the function of a gene or its role in pathogenesis in case of an infective microbe. Genetic engineering and manipulation of genes have been
